저어널 베어링의 온도 특성에 관한 실험적 연구

Abstract

This paper deals with some thermal characteristics of journal bearing such as the behavior of the maximum bearing temperature, the lubricant’s carry-over in the inlet region and so on. Temperatures of the bearing and the lubricants being supplied and discharged were measured along with shaft speed and bearing load. The results showed that with the increase of the shaft speed, the maximum temperature rose at any shaft speed at a different rate of change defending o the flow regime of the lubricant film. And the lower eccentricity ratio is the more lubricant’s carry-over occurs. Additionally it is partially proved that the oil discharge temperature and the maximum temperature changed in quite different each other.
